Y `I ljiis invention relates to new and useful iinrovements in a non-slip shoelace device.

More particularly, the invention contemplates the association of a leaf spring with an eyelet for a lace, arranged to releasably hold the shoelace Y from slipping. This construction has numerous advantages. 'The shoe laces on shoes are continually becoming loose while walking, requiring frequent adjustments. While the invention is particularly intended for shoes, it may be used for other articles wherever laces are used, as for example, corsets and other garments.

The invention also proposes numerous modifications one of which includes means for holding the leaf spring in a lifted position so that the lace may freely pass, when this is desired.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure: Y

Fig. 1 is a side elevational view of a shoe constructed in accordance with this invention.

Fig. 2 is a fragmentary plan view of a portion of Fig. 1 showing the details of one of the eyelets.

Fig. 3 is a fragmentary enlarged vertical sectional view taken on the line 3-3 of Fig. 2.

Fig. 4 is a view similar to Fig. 2 but illustrating a modified construction.

Fig. 5 is an enlarged vertical sectional view taken on the line 5-5 of Fig. 4.

Fig. 6 is a perspective View of the slide shown in Figs. 4 and 5.

The non-slip shoelace device, in accordance with this invention, includes an eyelet I0 for a lace I I. This eyelet has a friction gripping portion I 2. A leaf spring I3 is mounted on the eyelet I0 and is directed towards said friction gripping portion I2 for forcing and clamping said lace against said gripping portion.

The leaf spring I 3 is attached at one of its ends I4 to one of the flanges I5 of the eyelet I 0. A rivet I6 serves for this attachment, though these parts may be connected in other ways. The leaf spring I3 extends through the eyelet I0 and over a section of the lace I I. The top end of the leaf spring I3 is formed with serrations II which engage the lace I I and press it against the roughened friction gripping portion I2.

In Fig. 1 a shoe I 1' is illustrated provided with customary eyelets I 8. However, the top eyelet, indicated by reference numeral I8,is of the improved constructic'm-. -This shoe is shown having said lace II in'vposit-iomlaced 'through all eyelets. -Thefoperation of this form of the inventionV is as'follows:` f l y Y' The lace II is engaged-through the eyelet in vthe usual way. Itis drawn tight andthe serra- Y tions Il will -press the lace against the roughened portion I 2 for gripping same and holding it from slipping back. The lace is tied in the usual way.

When it is desired to remove the shoe, the lace is rst untied. Then the leaf spring I3 is lifted up with the fingers so that the lace II is freed, and then it is pulled through theeyelet.

`In Figs. 4-6 a modied form of the invention has beendisclosed which is very similar to the first form of the invention, distinguishing merely in the fact that a slide 20 has been mounted on the leaf spring I3 and is associated with certain holding means by which the leaf spring I3 may be held in an inoperative position. The leaf spring I3 is shown attached to Vthe eyelet Ill' by weldedV h points 2| and 22. The sud@ zo has anger-'like portions 23 projecting from its sides. These f finger-like portions 23 are engageable behind certain hook-like projections 24 formed along thev sides of the top flangeof the eyelet I0.

The operation of this form of the invention is identical to the prior form, except that when it is desired to free the lace II, the slide 20 maybe moved back on the leaf spring I3 so that the fingers 23 engage behind certain of the projections 24 and hold the leaf spring I3 in a raised position. The lace is now free.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the `scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
